AD: Sierra Hotel Aero (Navion)

AD NUMBER: 2008-05-14
MANUFACTURER: Sierra Hotel Aero Inc
SUBJECT: Airworthiness Directive 2008-05-14
SUMMARY:
The FAA adopts a new airworthiness directive (AD) for all Sierra Hotel Aero, Inc. (formerly Navion Aircraft LLC) Models Navion (L-17A), Navion A (L-17B), (L-17C), Navion B, Navion D, Navion E, Navion F, Navion G, and Navion H airplanes.

This AD requires you to do a one-time inspection of the entire fuel system and repetitive functional tests of certain fuel selector valves.

This AD results from reports of airplane accidents associated with leaking or improperly operating fuel selector valves.

We are issuing this AD to detect and correct fuel system leaks or improperly operating fuel selector valves, which could result in the disruption of fuel flow to the engine. This failure could lead to engine power loss.
